摘　　要：通过热电偶在位监控,研究了CF/PPS热塑复材试片感应焊接过程中的温度变化过程及温度分布情况。在此基础上探索了试片感应焊接工艺,重点研究了风冷、加压两种工艺方法对感应焊接效果的影响。观察了焊接试片形貌,分析了焊接工艺参数、方法对焊接试片形貌的影响。测试了感应焊接试片的单搭接强度,并与模压制造的单搭接试片性能进行了对比,提出了对工艺方法进一步改进的设想。This paper studied the temperature history and distributions at key positions during induction welding of thermoplastic composites.Carbon fiber reinforced poly(phenylene sulfide)(CF/PPS)coupons were fabricated,with in-situ thermocouple monitoring.Effects of welding parameters on surface morphology were explored,along with fundamental influences from air cooling and sustaining press.We further evaluated single-lap-shear strength and compared with data from hot pressing.Finally,some approaches were suggested for processing improvements.
